Your filter system could be called the heart of your pool, as it is integral to maintaining water
quality. It is the filter, along with a good chemical routine, which enables you to experience clean,
clear, healthy pool water with minimal effort. The filter system consists of the filter tank, pump and
motor. More details on the pump and motor can be found in the

Diatomaceous Earth
There are three types of filters: Cartridge, Diatomaceous Earth (D.E.) and Sand. Each system offers
specific advantages, and differ slightly in operation and the type of media that actually filters the
water (media refers to the sand, cartridge or D.E. inside the tank). Your Great Escape professional
will assist you in selecting the best filter type and model for your pool. The following pages provide
instructions for each type of filter. If you are shopping for a new filter system

Regardless of the type, your filter system should run 8 to 12 hours per day, or 24 hours a day on low
speed. When starting the filter for the first time make a note of the reading on the filter’s pressure
gauge once media has been added.
The initial reading is referred to as the normal starting
pressure, which can vary from system to system. As dirt and debris accumulate within the
filter the pressure gauge on the tank will rise, while simultaneously the return flow of water
going back to the pool diminishes. When the pressure gauge rises 7-10 psi above the
normal starting pressure it is time to backwash or clean the filter. Refer to instructions on
the following pages.
Cartridge filters consist of a tank that contains 1 or more pleated elements or cartridges that trap dirt
and debris within the pleats. Two unique advantages to this type of system are less water loss
than filters requiring backwashing and minimal maintenance. As stated, cartridge filters do not
require backwashing but the cartridge element itself should be removed
and cleaned as needed.
Cleaning requirements vary based on water quality but in a well maintained pool could be as little
as 2 to 3 times per season. Cartridge filters actually utilize the
debris they collect as an aid to
improve filtration. As a result, cleaning too often does not allow
the filter to work at optimum
filtration efficiency, while not cleaning often enough will shorten
the life of a cartridge element.
When the pressure gauge reads 7-10 psi above the “normal” or
starting reading you should follow
the steps below to remove and clean the cartridge element
or follow the manufacturer’s
instructions provided in the manuals below or that came with your filter.
Shut off pump & motor.
Close valves or plug off skimmer &
return lines to prevent water loss from pool.
Release pressure in the tank
by loosening the air relief bleeder valve.
Remove drain plug, allow water to drain from filter, close drain plug.
Unscrew and remove locking knob (counterclockwise direction) or clamp and carefully lift
off top cover to gain access to filter cartridge.
Remove cartridge element and using a garden hose with a pressure or
spray nozzle thoroughly rinse element top to bottom holding the
nozzle at a 45 degree angle, and wash all the pleats, with
particular emphasis between pleats.

Diatomaceous Earth (D.E.) is a fossil material ground into a very fine white powder. The D.E.
powder coats the internal elements (flex-tubes) inside the filter tank and as water passes through
the system, dirt. Algae, and some forms of
bacteria are strained from the water. If you are
shopping for a new filter system your Great Escape professional will be happy to help you find
the model that is right for your pool.

Adding DE
(Charging the filter)
On initial start-up and after each backwash, D.E. should be added to charge the
system within 1 minute of starting the pump & motor.
D.E. powder is measured
in pounds. D.E. Scoops are available as a convenient method of measuring and
adding D.E.
The amount required for each Hayward Perflex filter model is:
EC 45
4 lbs.
EC 65
EC 75
With pump running, add D.E. powder into the skimmer 1 scoop or lb. at a time,
as fast as the plumbing will take it.
Regeneration (Bumping)
As dirt collects inside the filter the pressure gauge increases while return flow to the pool
When the pressure increases 7-10 psi above the normal starting pressure it’s time to
bump or regenerate the system following the instructions below. This process drops dirt & debris
that collected on the D.E. coated tubes & drops to the bottom of the tank, exposing a clean layer
of D.E., lowering the pressure and extending the cycle. If the pool is very dirty or has a lot of
algae, the filter may require frequent backwashing, as the D.E. saturates quickly.
Turn off the pump & motor.
Open the air relief bleeder valve on top of the tank.
Bump handle down slowly and up briskly, 3 times.
With the air bleeder valve open, turn the motor back on
and when water sprays out of air bleeder close valve.
open the air bleeder valve each time you start up your system to
relieve pressure.
When regeneration process no longer lowers the pressure (after 1 or 2 cycles of bumping) you
need to clean the filter of the old D.E. and dirt that has collected inside the tank. You will know its
time to backwash when the pressure goes back up shortly after regenerating, signaling the D.E.
has become completely saturated with dirt and needs to be replaced.
Cleaning using water flow
Backwashing is recommended when the pressure gauge rises more than 10 psi in less than
a 24 hour period or when cloudy water returns to the pool for longer than 30
seconds after
regeneration. Before backwashing make sure the backwash hose,

, is extended to an appropriate area to discharge used D.E., dirt,
and water.
Turn off pump & motor.
Open the air relief bleeder valve on top of the tank.
Bump the handle down slow and up briskly 8 times.
Close valves (if used) at skimmer & return line or plug closed to prevent water loss from pool.
With backwash hose attached, open filter drain and allow water and dirt to empty
completely through the backwash hose.
After the filter has emptied and with the drain still open, open the valve or unplug the
skimmer line and allow water to run for a few seconds to flush out any remaining dirt or
debris from the bottom of the filter.
Close the filter drain open skimmer and return line valves, or unplug skimmer & return.
Start the pump & motor and close air bleeder valve when water sprays from it.
Allow filter to fill with water then repeat steps 1-8 and go through another cleaning cycle.
After the 2
cleaning cycle is completed recharge with D.E. following instructions
on previous page for adding D.E. Add D.E. within 1-2 minutes of starting system.

: All suction and discharge valves must be open and or plugs removed before
starting system. Failure to
do so could cause severe personal injury and/or property damage.
Chemical Cleaning
Nature’s Way
Cartridge Renu
click to purchase
, per label directions
provides a more thoroughly cleaning of the flex-tubes inside your D.E. filter and
extends the time between regeneration or backwash cycles.
While Perflex filters are basically resistant to the difficulties often encountered as a
result of chemical build-up in swimming pools, it is important to keep in mind that the
mineral content in a pool increases every day as a result of the chemicals added and
the normal water evaporation process. If the concentration of minerals is allowed to
get too high, the minerals will form deposits on the Flex-Tubes inside the filter, and
will eventually result in shortened filter cycles. To guard against this, a yearly chemical cleaning
(soaking) of the Flex-Tube assembly is suggested. Use commercially available 20% muriatic
acid added to water in 1 to 1 ratio; or use other commercial filter element cleaner mixed
according to the package instructions. Use a plastic container and take extreme caution when
handling cleaning agents as they can be harmful to the eyes, skin and clothing. After cleaning,
thoroughly flush all affected parts with cold water. See
Chemical Safety
for additional
recommendations and follow all label instructions for safe handling and usage.

In a sand filter water passes through the pump housing and enters the filter through the
multiport valve head, which controls the directional flow of the water.
As water passes
through a bed of filter sand (silica quartz) dirt is trapped in the sand bed and clean
filtered water is returned to the pool.
As with all filter systems, your sand filter should run
8 to 12 hours a day. When the filter becomes dirty- pressure builds in the sand filter and
the water flow returning to your pool decreases.
When you initially start your sand filter
you will want to make a mental note of the “normal” or “starting pressure”, when the reading
increases 7-10 psi above that normal starting reading you should clean the sand by backwashing
the filter. Backwashing involves reversing water flow through the filter and sending dirt through a
waste line. A valve on the filter tank will direct the water to control backwashing and other functions.
The following are GENERAL guidelines for operating a sand filter. Specific instructions on the
operation of your filter model can be found on the following page.
- This is the process by which the water from the pool passes through the
filter tank and the sand. As the water trickles down through the sand, the dirt and debris are
trapped by the sand, thus filtering the water. The filter should run 8-12 hours a day.
- This process is used to clean
the debris that has accumulated, out of the sand. The
water is essentially moving in a reverse fashion. This
should not be done for more than one minute at a time,
and should be done when the flow of water back to the
pool has slowed considerably and the pressure gauge
has doubled the original normal starting pressure.
- This is done after backwashing to
settle the sand & cloudy water inside the tank caused
by backwashing, so sediment won’t pass back into pool.
- Water is passed from the
skimmer to the pump and then up to the valve; however,
instead of passing through the sand, it passes through
the valve head and then back into the pool. Re-circulate
is used to circulate chemicals without filtering; this will
simply circulate the water throughout the pool.
- this function is used when one desires to draw water or vacuum debris
from the pool directly onto the ground (bypassing the tank). For example, if there is a lot of
debris accumulated on the floor of the pool, one would use this process to vacuum it from the
pool onto the ground; bypassing the filter tank.
- this position is used when one wishes to shut off water flow through the
valve. The valve is left in this position for winterizing, since it shuts off all of the passageways
through the valve.
For optimum performance the o-rings inside the multiport valve, filter tank, and
pump should be lubricated regularly with o-ring lube,

DO NOT use vaseline® as the petroleum can breakdown the rubber material.
When the return flow diminishes and your filter pressure gauge rises
8-10 psi higher than the normal starting pressure it is time to backwash.
Turn off pump and motor and open filter air relief valve.
Depress valve handle and rotate to BACKWASH position.
With backwash hose,
click to purchase
, extended to an appropriate area to
discharge water; open drain at bottom of tank or optional backwash gate or ball valve.
Turn pump on and backwash until water in sight glass is clear. Approximately
2 minutes or less depending on dirt accumulation. Proceed to RINSE
Turn pump off, depress valve handle and rotate to rinse position.
Turn on pump for 30 seconds to 1 minute, to ensure all dirty water from backwashing is rinsed out
of the filter to waste, preventing return to pool.
Turn pump off, depress handle and turn to FILTER position.
Open air relief bleeder valve, close backwash gate or ball valve (optional) or thread drain cap on.
Turn on pump and motor and close air bleeder valve when water sprays out.
IMPORTANT notes to remember when backwashing
Allow filter to backwash until water exiting the waste line is clear.
backwashing can
remove 50 -300 gallons of water from your pool so pay close attention to the sight glass and or
Also, be aware of local codes regarding pool water disposal as some communities
have specific guidelines involving drainage.
Don’t backwash excessively. Sand filters operate more efficiently during mid-cycle. Some level
of debris in the sand bed actually helps filtration and makes the filter more effective. Too much
backwashing can reduce efficiency.
Sand should be replaced every 1-2 seasons. U se only swimming pool filter quartz referred to
as #20 silica sand, DO NOT use play sand. When replacing sand be careful of the bottom
laterals (slotted tubes) at the bottom of the filter tank and follow your filter manual instructions
for adding sand. When changing sand check laterals for cracks and replace if necessary.
